Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an integrated anaerobic fermentation purification device for domestic wastewater. Background Technology

[0002] Wastewater treatment is an important task for protecting the environment and human health. In the treatment process, wastewater first passes through a screen to remove larger suspended solids and floating matter, and then enters a sedimentation tank to remove solid particles through gravity settling. After sedimentation, the wastewater passes through a sand filter to remove smaller suspended solids and some organic matter. Then, the wastewater is transported to an equalization tank for water quality adjustment to ensure the stability of subsequent treatment processes.

[0003] The regulated wastewater first enters an anaerobic tank for anaerobic fermentation to remove organic pollutants and some nitrogen and phosphorus pollutants. Then, the wastewater is transported to an aerated sedimentation tank, where the activated sludge process is used to further degrade organic matter. The next treatment steps include a chemical sedimentation tank, where chemical agents are added to remove phosphorus and difficult-to-degrade organic matter from the water. Finally, the wastewater is treated by filtration and disinfection equipment to ensure that pathogenic microorganisms are effectively removed, thereby enabling the wastewater to reach higher purification standards and meet specific discharge requirements or reuse water standards.

[0004] The wastewater in the anaerobic tank is treated using anaerobic biological fermentation. Under anaerobic conditions, the organic matter in the wastewater is decomposed, metabolized, and digested by anaerobic bacteria, resulting in a significant reduction in the organic matter content of the wastewater. At the same time, biogas is produced, making it a highly efficient wastewater treatment method. In addition, the anaerobic tank is equipped with a combination of packing materials, which are used to provide a surface for microorganisms to attach to and are an important part of the anaerobic fermentation process.

[0005] However, over time, the surface of the packing material in the anaerobic tank can become clogged due to sludge accumulation or the adhesion of other pollutants, resulting in a reduction in the number and activity of microorganisms on the surface of the combined packing material. This reduces the ability of microorganisms in the anaerobic tank to degrade organic matter. In order to restore the treatment effect, it is necessary to empty the anaerobic tank regularly and clean or replace the combined packing material. This means that cleaning the combined packing material takes a lot of time, thereby reducing the efficiency of anaerobic fermentation and purification of wastewater.

[0006] In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes an integrated anaerobic fermentation purification device for domestic sewage, which solves the above-mentioned technical problems. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention proposes an integrated anaerobic fermentation purification device for domestic sewage. This invention utilizes a mounting spring and a mounting rod, whereby the drive motor rotates the worm gear, which in turn drives the mounting rod through a meshing worm wheel. This causes the mounting rod to synchronously rotate the mounting spring and the fiber packing material, agitating the sewage and creating flow within the purification chamber. The sewage impacts the sludge on the surface of the fiber packing material, removing it and increasing the amount of microorganisms attached to the packing surface, thus enhancing the microbial degradation capacity of the sewage. Furthermore, this invention eliminates the need for periodic emptying of the anaerobic tank and cleaning or replacement of the combined packing material, thereby improving the efficiency of anaerobic fermentation purification of sewage.

[0008] The technical solution adopted by this invention to solve its technical problem is as follows: The integrated anaerobic fermentation purification device for domestic sewage of this invention includes a box body; a partition is fixedly connected inside the box body; the space inside the box body is sequentially divided into an adjustment chamber and a purification chamber by the partition; an inlet is opened on one side of the adjustment chamber; an outlet is opened on one side of the purification chamber; fiber packing is installed in the purification chamber; an exhaust hole is opened at the upper end of the purification chamber; a water pump is installed in the adjustment chamber; the water pump is connected to the purification chamber through a drain pipe; a crossbeam is fixedly connected to the inner wall of the purification chamber; an installation rod is rotatably connected to the lower end of the crossbeam; a connecting plate is fixedly connected to the surface of the installation rod; an installation spring is sleeved on the surface of the installation rod; the fiber packing is fixedly connected to the surface of the installation spring; the installation spring is fixedly connected to the connecting plate; a cavity is opened inside the crossbeam; a worm gear and a worm are rotatably connected in the cavity; the worm gear meshes with the worm gear; the worm gear is fixedly connected to the installation rod; a drive motor is fixedly installed on one side of the box body; the drive motor is used to drive the worm gear to rotate.

[0009] Preferably, at least five worm gears are provided; a gear is fixedly connected to the surface of the worm gear; a transmission belt is sleeved on the surface of the gear; and a meshing groove for meshing with the gear is formed on the inner ring wall of the transmission belt.

[0010] Preferably, the connecting plate has an air cavity inside; a rotating wheel is rotatably connected inside the air cavity; a connecting ring is fixedly connected to the lower end of the mounting spring; the rotating wheel is fixedly connected to the connecting ring by a steel wire rope; a slot is opened on the lower end face of the mounting rod; an insert rod is slidably connected inside the slot; a slot that mates with the insert rod is opened on the upper end of the rotating wheel; a magnet is fixedly connected to the end of the insert rod near the bottom of the slot; an electromagnetic plate is embedded in the bottom of the slot.

[0011] Preferably, the rotating wheel is configured as an annular shape; the rotating wheel is connected to the inner wall of the air chamber by a spring.

[0012] Preferably, the mounting rod has a groove on its surface; an oscillating rod is slidably and sealed within the groove; the oscillating rod is connected to the bottom of the groove by a fixed spring; and an electromagnetic ring is embedded in the bottom of the groove.

[0013] Preferably, a striking plate is fixedly connected to the end of the oscillating rod away from the groove; the striking plate is configured to be arc-shaped.

[0014] Preferably, the bottom of the housing has a sludge discharge chamber; a push plate is slidably and sealingly connected inside the sludge discharge chamber; a screw is rotatably connected inside the sludge discharge chamber; the screw is helically driven to the push plate; a servo motor is fixedly installed on one side of the housing; the servo motor drives the screw to rotate; a through hole communicating with the sludge discharge chamber is opened at the bottom of the purification chamber; a sewage outlet communicating with the sludge discharge chamber is opened at the bottom of the housing; a sealing plate is rotatably installed inside the sewage outlet.

[0015] Preferably, both the oscillating rod and the screw surface are fitted with a corrugated tube; the corrugated tube is made of PTFE material.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention, by setting up an installation spring and an installation rod, allows the worm gear driven by the drive motor to rotate, which in turn drives the installation rod to rotate through a meshing worm wheel. This causes the installation rod to drive the installation spring and the fiber packing to rotate synchronously, agitating the wastewater and causing it to flow within the purification chamber. The wastewater impacts the sludge on the surface of the fiber packing, removing it and increasing the amount of microorganisms attached to the packing surface, thus enhancing the microbial degradation capacity of the wastewater. Simultaneously, it eliminates the need for periodic emptying of the anaerobic tank and cleaning or replacement of the combined packing, thereby improving the efficiency of anaerobic fermentation purification of wastewater.

[0018] 2. By setting up an oscillating rod, the present invention can apply an impact force to the mounting spring, which in turn causes the mounting spring to vibrate the fiber packing material on the surface. This reduces the adhesion strength of the sludge particles on the surface of the fiber packing material, making it easier for the sludge on the surface of the fiber packing material to be carried away or dispersed by the water flow. This accelerates the cleaning effect of the sludge on the surface of the fiber packing material and improves the efficiency of the present invention in anaerobic fermentation and purification of sewage.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1 to 5As shown, the integrated anaerobic fermentation purification device for domestic sewage of the present invention includes a housing 1; a partition 11 is fixedly connected inside the housing 1; the space inside the housing 1 is sequentially divided into an regulating chamber 111 and a purification chamber 112 by the partition 11; an inlet 113 is provided on one side of the regulating chamber 111; an outlet 114 is provided on one side of the purification chamber 112; fiber packing material 12 is installed inside the purification chamber 112; an exhaust vent 115 is provided at the upper end of the purification chamber 112; a water pump 116 is installed inside the regulating chamber 111; the water pump 116 is connected to the purification chamber 112 through a drain pipe; a crossbeam 1 is fixedly connected to the inner wall of the purification chamber 112. 3; A mounting rod 131 is rotatably connected to the lower end of the crossbeam 13; a connecting plate 14 is fixedly connected to the surface of the mounting rod 131; a mounting spring 132 is sleeved on the surface of the mounting rod 131; the fiber filler 12 is fixedly connected to the surface of the mounting spring 132; the mounting spring 132 is fixedly connected to the connecting plate 14; a cavity 133 is opened inside the crossbeam 13; a worm gear 134 and a worm 135 are rotatably connected inside the cavity 133; the worm 135 meshes with the worm gear 134; the worm gear 134 is fixedly connected to the mounting rod 131; a drive motor 15 is fixedly installed on one side of the housing 1; the drive motor 15 is used to drive the worm 135 to rotate.

[0028] In one embodiment of the present invention, at least five worm gears 135 are provided; a gear 151 is fixedly connected to the surface of the worm gear 135; a transmission belt 152 is sleeved on the surface of the gear 151; and a meshing groove for meshing with the gear 151 is formed on the inner ring wall of the transmission belt 152.

[0029] In one embodiment of the present invention, the connecting plate 14 has an air cavity 141 inside; a rotating wheel 142 is rotatably connected inside the air cavity 141; a connecting ring 136 is fixedly connected to the lower end of the mounting spring 132; the rotating wheel 142 is fixedly connected to the connecting ring 136 by a steel wire rope 153; a slot 143 is opened on the lower end face of the mounting rod 131; an insert rod 144 is slidably connected inside the slot 143; a slot 145 that mates with the insert rod 144 is opened on the upper end of the rotating wheel 142; a magnet 146 is fixedly connected to one end of the insert rod 144 near the bottom of the slot 143; an electromagnetic plate 147 is embedded in the bottom of the slot 143.

[0030] In one embodiment of the present invention, the rotating wheel 142 is configured as an annular shape; the rotating wheel 142 is connected to the inner wall of the air chamber 141 by a spring 148.

[0031] During operation, over time, the surface of the packing material in the anaerobic tank can become clogged due to sludge accumulation or the adhesion of other pollutants. This reduces the amount of microorganisms attached to the surface of the packing material, thus decreasing the number and activity of microorganisms in the anaerobic tank and affecting its ability to degrade organic matter. To restore the treatment effect, the anaerobic tank needs to be emptied regularly, and the packing material needs to be cleaned or replaced. This results in a significant time commitment for cleaning the packing material, thereby reducing the efficiency of anaerobic fermentation and purification of wastewater.

[0032] To address this issue, the present invention incorporates a mounting spring 132 and a mounting rod 131. During the rotation of the worm gear 135 driven by the drive motor 15, the worm gear 135 drives the mounting rod 131 to rotate via a meshing worm wheel 134. This causes the mounting rod 131 to synchronously rotate the mounting spring 132 and the fiber packing 12. The rotating fiber packing 12 agitates the wastewater, causing it to flow within the purification chamber 112. This impacts the sludge on the surface of the fiber packing 12, removing the sludge and increasing the amount of microorganisms attached to the packing surface. This enhances the microbial degradation capacity of the wastewater. Furthermore, the invention eliminates the need for periodic emptying of the anaerobic tank and cleaning or replacement of the combined packing material, thereby improving the efficiency of anaerobic fermentation purification of wastewater.

[0033] The types of composite packing materials include fiber bundles, plastic sheets, sleeves, and central ropes. Among them, fiber packing materials made of polyolefin fiber bundles are widely used because the woven structure of the fiber bundles gives them a large specific surface area, which can provide more attachment points for microorganisms. Polyolefin materials are not only inexpensive, but also have extremely strong corrosion resistance, which can effectively resist the erosion of the packing materials by chemicals, acid and alkaline pollutants in sewage.

[0034] In use, the user connects the inlet 113 to the external sewage conveying pipe. The inlet 113 is connected to the external conveying device through the conveying pipe, allowing the external conveying device to transport the sewage in the purification chamber 112 for further treatment. After the sewage is transported into the regulating chamber 111 through the sewage conveying pipe, the user adds a neutralizing agent to the regulating chamber 111 to adjust the pH value of the sewage in the regulating chamber 111, so as to prevent the pH value fluctuation of the sewage from affecting the activity of microorganisms. After the pH value of the sewage is adjusted, the user controls the water pump 116 to transport the sewage in the regulating chamber 111 into the purification chamber 112 for anaerobic fermentation treatment. Since the exhaust port 115 is connected to the external gas collection tank through the gas conveying pipe, the biogas obtained by the anaerobic fermentation of the sewage in the purification chamber 112 will be transported to the external gas collection tank through the exhaust port 115, so that the gas collection tank can collect the biogas obtained by anaerobic fermentation.

[0035] Over time, the surface of the anaerobic tank packing material will become clogged due to sludge accumulation or the adhesion of other pollutants. When the user needs to clean the fiber packing material 12, simply control the drive motor 15 to drive the worm gear 135 to rotate. The worm gear 135 will then drive the meshing worm wheel 134 to rotate, which in turn will drive the mounting rod 131 fixed to it to rotate. The mounting rod 131, through the connecting plate 14 fixed to it, will drive the mounting spring 132 to rotate. During this rotation, the mounting spring 132 will agitate the sewage in the purification chamber 112, causing the sewage to flow. This flowing sewage will then clean the rotating fiber packing material 12. The flushing action removes the sludge adhering to the surface of the fiber packing 12, allowing sufficient microorganisms to adhere to the surface of the fiber packing 12. This increases the number and activity of microorganisms in the purification chamber 112, thereby enhancing the ability of microorganisms in the purification chamber 112 to degrade organic matter. Through the cooperation of gear 151 and transmission belt 152, the transmission belt 152 has a meshing groove with the inner ring, allowing the gear 151 and the transmission belt 152 to mesh. This improves the transmission effect between the transmission belt 152 and multiple worm gears 135 through gear 151, thereby ensuring that the drive motor 15 can stably drive multiple screws 172 to rotate synchronously, so that the installed spring 132 can drive the fiber packing 12 to rotate stably.

[0036] Furthermore, by increasing the rotation speed of the drive motor 15, the drive motor 15 drives the mounting spring 132 to rotate at a higher speed via the screw 172. This causes the mounting spring 132 to rotate the fiber packing 12 faster. When the fiber packing 12 rotates, the sludge attached to its surface is subjected to centrifugal force. Therefore, increasing the rotation speed of the drive motor 15 increases the centrifugal force on the sludge, thereby accelerating the sludge detachment from the surface of the fiber packing 12 and further reducing the amount of sludge attached to the surface of the fiber packing 12. Moreover, when the sewage is agitated, the flowing sewage can carry nutrients such as nitrogen and phosphorus in the sewage to be evenly distributed in the sewage. This allows these nutrients to stimulate the growth and metabolism of microorganisms on the surface of the fiber packing 12, promoting better degradation of organic matter. This improves the effect of the present invention on anaerobic fermentation purification of sewage.

[0037] During the rotation of the mounting spring 132 driven by the drive motor 15, the user controls the electromagnetic plate 147 to generate the same magnetic poles as the magnet 146. This causes the magnet 146 to push the insertion rod 144 out of the slot 143 and closer to the rotating wheel 142 under the influence of magnetic repulsion. Since the mounting rod 131 rotates, it drives the rotating wheel 142 to rotate via the connecting plate 14. Therefore, when the insertion rod 144 contacts the rotating wheel 142, a sliding contact occurs between them until the rotating wheel 142 moves the slot. 145 is aligned with the insertion rod 144, causing the insertion rod 144 to enter the slot 145 under the magnetic repulsion of the magnet 146. This causes the insertion rod 144 to block the rotation of the rotating wheel 142 through the slot 145. At this time, the rotating wheel 142 is connected to the crossbeam 13 through the insertion rod 144, causing the rotating wheel 142 and the connecting plate 14 to rotate relative to each other. Since the rotating wheel 142 and the connecting ring 136 are connected by a steel wire rope 153, and the connecting plate 14 drives the connecting ring 136 to rotate synchronously through the installed spring 132, the rotating wheel 142 and the connecting ring 136 rotate in opposite directions. The rotating wheel 142 rotates in opposite directions. 42 will pull the steel wire rope 153 to rotate, causing the steel wire rope 153 to wind around its surface. This causes the end of the steel wire rope 153 connected to the connecting ring 136 to pull the mounting spring 132 to extend until the mainspring 148 is fully wound. At this point, the mounting spring 132 has reached its maximum extension. At this time, the control electromagnetic plate 147 is de-energized, so that the electromagnetic plate 147 no longer generates a magnetic repulsive force on the magnet 146. This causes the magnet 146 to generate a magnetic attraction force on the bottom of the slot 143, causing the magnet 146 to drive the insertion rod 144 into the slot 143, thus preventing the rotating wheel 142 from contacting the horizontal... When beam 13 is connected, the wheel 142 rotates in the opposite direction under the restoring force of the spring 148, causing the wire rope 153 to be released. At this time, the wire rope 153 no longer applies tension to the mounting spring 132, causing the mounting spring 132 to contract under its own restoring force. This causes the mounting spring 132 to drive the fiber packing 12 to shake up and down and rotate, thereby improving the interaction between the fiber packing 12 and the flowing sewage. This not only helps the casing to clean the fiber packing 12 and increase the amount of microorganisms attached, but also accelerates the sludge removal efficiency on the surface of the fiber packing 12.

[0038] In one embodiment of the present invention, a groove 16 is provided on the surface of the mounting rod 131; an oscillating rod 161 is slidably and sealed within the groove 16; the oscillating rod 161 is connected to the bottom of the groove 16 by a fixing spring 162; and an electromagnetic ring 163 is embedded in the bottom of the groove 16.

[0039] In one embodiment of the present invention, a striking plate 164 is fixedly connected to the end of the oscillating rod 161 away from the groove 16; the striking plate 164 is configured to be arc-shaped.

[0040] In one embodiment of the present invention, a sludge discharge chamber 17 is provided at the bottom of the housing 1; a push plate 171 is slidably and sealingly connected inside the sludge discharge chamber 17; a screw 172 is rotatably connected inside the sludge discharge chamber 17; the screw 172 and the push plate 171 are connected by a helical transmission; a servo motor 173 is fixedly installed on one side of the housing 1; the servo motor 173 is used to drive the screw 172 to rotate; a through hole 18 communicating with the sludge discharge chamber 17 is provided at the bottom of the purification chamber 112; a sewage outlet 19 communicating with the sludge discharge chamber 17 is provided at the bottom of the housing 1; a sealing plate 191 is rotatably installed inside the sewage outlet 19.

[0041] In one embodiment of the present invention, both the oscillating rod 161 and the screw 172 are fitted with a bellows 2; the bellows 2 is made of PTFE material.

[0042] During operation, in order to further improve the cleaning effect of sludge adhering to the surface of the fiber packing 12, the present invention sets up an oscillating rod 161, which can apply an impact force to the mounting spring 132. The impacted mounting spring 132 can drive the fiber packing 12 on the surface to vibrate, thereby reducing the adhesion strength of the sludge particles adhering to the surface of the fiber packing 12. This makes it easier for the sludge adhering to the surface of the fiber packing 12 to be carried away or dispersed by the water flow, thereby accelerating the cleaning effect of the sludge adhering to the surface of the fiber packing 12 and improving the efficiency of the present invention in anaerobic fermentation purification of sewage.

[0043] In use, the user controls the electromagnetic ring 163 to be energized, causing it to attract the oscillating rod 161 and compress the fixing spring 162 into the groove 16. This causes the oscillating rod 161 to pull the striking plate 164 closer to the mounting rod 131. Once the oscillating rod 161 is fully inside the groove 16, the user controls the electromagnetic ring 163 to be de-energized. This causes the oscillating rod 161 to extend out of the groove 16 under the restoring force of the fixing spring 162. The oscillating rod 161 then pushes the striking plate 164 closer to the mounting spring 132 until the striking plate 164 and the mounting spring 132 collide and make contact. When the mounting spring 132 is impacted, it vibrates, which transmits the vibration to the fiber filler 12 fixed to the surface. The vibration formed on the surface of the fiber filler 12 helps to break up the sludge adhering to the surface, making it easier to remove the sludge when the flowing sewage impacts it. The reason why the striking plate 164 is set in an arc shape is that when the mounting spring 132 extends and vibrates, the arc-shaped striking plate 164 will not be inserted into the pitch gap of the mounting spring 132, thereby avoiding interference with the extension and vibration of the mounting spring 132.

[0044] After the sludge detaches from the surface of the fiber packing 12, it settles at the bottom of the purification chamber 112. Through holes 18 at the bottom of the purification chamber 112, the settled sludge falls into the sludge discharge chamber 17, reducing the sludge content in the purification chamber 112. This prevents the sludge from being stirred up during subsequent agitation of the wastewater flow in the purification chamber 112, thus reducing the sludge content in the wastewater and consequently decreasing the sludge adhesion rate on the surface of the fiber packing 12. As the sludge settles in the sludge discharge chamber 17, the user controls the servo motor 173 to drive the screw 172, which in turn drives the push plate 171 to slide within the sludge discharge chamber 17. The push plate 171 then pushes the sludge in the sludge discharge chamber 17 to the discharge port 19. Located below the regulating chamber 111, and with the push plate 171 in sliding and sealed contact with the inside of the sludge discharge chamber 17, the user only needs to open the sealing plate 191 at the sewage outlet 19 to clean the sludge. The corrugated pipe 2 is provided on both the surface of the vibrating rod 161 and the screw 172 to prevent sewage from entering the groove 16 and to prevent sludge from clogging the threaded groove on the surface of the screw 172. This prevents sewage from corroding the electromagnetic ring 163 in the groove 16 and avoids sludge clogging the screw 172, preventing it from driving the push plate 171 to move in the sludge discharge chamber 17. This ensures that the invention can operate normally and stably. By making the corrugated pipe 2 with PTFE material, the corrugated pipe 2 has a smooth surface and is corrosion resistant, which effectively improves the service life of the corrugated pipe 2.
